I have a question for Refresh Endura users (past or present (ie, Canadians). What is the best way to use this drop? When I use it alone, I find about an hour later, my eyes feel even more dry. I tried it over an aqueous drop (TheraTears) and I found it to be better, but am worried that there might be an interaction between the carboymethylcellulous sodium in the theratears and the carbomer/castor oil in the endura drops.
Also, I'm finding that the endura drops make my eyes fairly red - is this a temporary reaction that goes away with prolonged use? or might this be a sign of irritation?
Thanks!
